I BEER-COOLER.

SPECIFICATION forming part of Letters Patent No. 625,658, dated May 23,1899.

I Application filed September 27, 1898- Serial No. 691,967. (No model.)

class of beer-coolers in which the temperature of the beer is reducedafter leaving the barrel. Its object is to produce a beer-cooler withwhich the temperature of the beer or other liquids on draft in abar-room may be reduced without reducing the temperature of the entirecontents of the barrel or vessels from which the liquids are drawn;

To that end it consists in the arrangement of a water-tight insulatedcasing containing one or more pipe-coils so placed as to be submerged inwater, the temperature of which is reduced by ice floating on itssurface, said coils being connected at one end to the supply and at theother end to the discharge of the beer or other liquid to be cooled.

The invention further consists in other details of its construction andcombination of parts, all of which I will now proceed to defi nitelydescribe, and then point out in the claims that which I believe to benovel.

111 the drawings, Figure 1 is a central vertical section of abeer-cooler arranged according to my invention. Fig. 2 is a frontelevation of the same with portions broken away to show construction.Fig. 3 is a detail view of one of the connections to the coolingcoils,and Fig. 4"is a detail view of the overflow-pipe connection.

Referring to the drawings, 1 is a box or casing, which is insulatedaround its side walls by the air-chambers 2. This casing is madewater-tight and is provided at its upper end with a hinged door or lid3. Mounted within the casing 1 are the pipe-coils 4, which are rigidlyheld in place by the vertical pipes 5, which in turn are held in placeby T-joints threaded into the cross-pipe 6, secured in the upper end ofthe casing 1.

7 are the supply-pipes, which are connected to the coils 4 by thefittings 8, a detail of which is shown in Fig. 3. These fittings 8 sealthe openings in'the floor of the casing 1, through which the liquidpasses on its way to the pipe-coils 4. The inner openings of saidfittings are trough-shaped to receive the ends of the pipe-coils 4 andare rounded off, as at 9, to avoid breaking the coil-pipe, which is bentat right angles at this point.

10 is an annular flange cast integral with the fitting 8. A leatherwasher 11 is placed under this flange 10, and the flange and washer arefirmly drawn against the floor of the casing by the nut 12, threadedover the outer end of the fitting.

The ends of the pipe-coil 4 and supply-pipe 7 are connectedby the union13, as seen in the drawings.

.14 is the discharge cook or faucet, (see Fig. 1,) which is connected bya union to the upper end of the pipe-coil.

15 is the overflow-pipe, the lower end of which is made tapering and isfitted into the sleeve 16. This sleeve 16 is provided with a flange 17at its inner end and projects through the floor of the casing, where itis securely held by the nut 19 and washer 18.

20 is a union similar to the union 13 and which connects the sleeve 16with the wastepipe 21. (See Fig.4.)

22 are small holes placed in the upper end of the overflow-pipe andthrough which the water passes on its way to the waste-pipe.

23 is a cross piece or pin secured at the top of the overflow-pipe, soplaced to assist the operator in removing said pipe, if desired.

In operation the cooler, as shown in the drawings, is arranged forbar-room service, and the supply of beer or other liquids, which areusually stored in the cellar, is connected to the supply-pipes 7,through which the liquids are forced up into the coils 4. The casing isnow filled with water and its tempera ture reduced by the introductionof ice, as shown in the drawings, and asthe coils are entirely submergedby reason of the overflowpipe it will be seen that said coils will bethoroughly subjected to the refrigeration of the cold water, which inturn receives its refrigeration from the ice placed into it. -As the iceis replenished the consequent overflow of Water is drawn off through theopenings 22 in the overflow-pipe 15, where it passes down to theWaste-pipe 21.

It will be seen that the overflow-pipe 15 may readily be removed, ifdesired, in cleaning the casing.

Having .thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In abeer-cooler, the combination with a casing, of a plurality ofstationary supports located in separated arrangement, a crosspiececonnecting said supports and bracing them, and beer conducting pipescoiled around the respective supports.

2. In a beer-cooler, the combination with a casing, of a plurality ofstationary, separated, supports disposed Within the casing, a crosspiececonnecting the supports to each other and having its ends secured to thewalls of the casing, and beer-conducting pipes coiled around therespective supports.

3. A beer-cooler comprising the following instrumentalities, 'to wit: acontaining-casing, a sleeve in the bottom of the casing provided with anopen mouth at its inner end, an overflow-pipe having its end detachablyshaped mouth, and a beer-conducting pipe extending through said fittingand bent to lie in the trough-shaped mouth.

5. In a beer-cooler, the combination with a casing, of a hollow fittingor sleeve having a threaded portion passed through one of the walls ofthe casing and provided with a flange and a trough-shapedlaterally-disposed mouth at one end, of a nut on theopposite threadedend of the sleeve, and a pipe passed through the sleeve or fitting andhavinga portion bent to lie in the trough-shaped mouth.

Signed by me, at Buffalo, New York, this 30th day of July, 1898.
